USBPrinter.connectPrinter(printer.vendorID, printer.productId).then(() => setCurrentPrinter(printer));

I'm trying to connect to a USB printer but when I'm tapping on the printer it's showing an error as mentioned below:

Attempt to invoke virtual method 'double java.lang.Double.doubleValue()' on a null object reference.
